Do I need to calibrate the Kevo fob with the lock?

While it is not necessary to calibrate the Kevo fob, it is recommended to do so for enhanced security purposes.

If the calibration results in a red flashing light ring at the end of the third touch sequence, then a poor calibration was performed.  This could be due to where you are carrying your Smartphone/Kevo fob.  You can accept a poor calibration, however accepting a poor calibration is not advised and could cause Kevo to be susceptible to unauthorized operation while your Smartphone/Kevo fob is inside of your home.  If you continue to have calibration issues, call Kevo support.
